MODERN WEAPON SYSTEMS

If you want the best bolt carrier on the market, you just found it. we custom machine our bolt carrier groups with a focus on tolerance and a unique, aggressive look that also reduces weight. We then coat the entire carrier with nickel boron. This coating gives the carrier extreme lubricity, stops the finish from wearing away with use, and makes cleaning the carrier as simple as wiping it with a dry rag. Simply put, this is the last bolt carrier you will ever need to buy for your rifle.

The real deal

I have a Rhino AR10 I had a dropped my carrier and damaged the bolt face, was concerned I would not find one. Came across MWS site and ordered one was a little worried it might not me real because the price was too good. Well I was wrong it was the same high end large rear bolt and carrier. These are the best low MOA bgc for 308 ever made. I have tried other including JP and this one always shoots better in my ar10 then even the $500.00 JP I bought.
